We want to create and study a function that models the given situation.
We will find that the correct option is:
"The values of both x and y will be real numbers greater than or equal to 0."
The information that we have is:
Peaches are being sold for $2 per lb.
Then if we define x as the number of pounds that you buy, and y as the cost of these peaches, we can write the function:
y = $2*x
Now we want to see which statement describes the values of x and y.
Let's analyze each statement:
1) "The values of both x and y can be any real number."
False, a real number is -3, and you can't buy a negative number of peaches.
2) "The values of both x and y will be real numbers greater than or equal to 0."
Here we removed the above problem, so this works fine.
3) "The value of x and y will always be zero"
No, you can buy 2 pounds of peaches and you will pay:
y = $2*2 = $4
So neither x nor y need to be zero.
4) The value of x can be any real number greater than or equal to 0, but the value of y must be an integer greater than or equal to 0.
Here we do not have problems, but there are some cases where the cost could be a fraction, like if you buy 0.25 lb of peaches:
y = $2*0.25 = $0.5
So the cost does not need to be an integer.
Finally, we can see that the correct option is:
"The values of both x and y will be real numbers greater than or equal to 0."
